__i3c_maste...c_dev_locked(9)

💅 NAME 💅

__i3c_master_add_i3c_dev_locked — bestie, this is the one that adds an I3C slave to the bus 🦋

---

✨ SYNOPSIS ✨

void __i3c_master_add_i3c_dev_locked (struct i3c_master_controller
*master , u8 addr , bool probe );

---

🎀 ARGUMENTS 🎀

• master — the master that's out here sending frames on the bus, no cap 🌈
• addr — the I3C slave dynamic address that got assigned to the device, iykyk
• probe — a bool that says "probe to see if the device is really present at addr" 👀 like we're checking if it actually showed up to the party

---

🫶 DESCRIPTION 🫶

Okay so picture this: this function instantiates an I3C device object and adds it to the I3C device list. That's the whole vibe. ✨ All the device information? Retrieved using standard CCC commands. Every single bit of it. Iconic behavior honestly.

⚠️ hard requirement alert — this function must be called with the bus lock held in write mode. Not read mode. Not "eh, close enough" mode. Write mode, periodt. 💀
